The method used to estimate ideal points for contributors is described in
"Ideology and Interests in the Political Marketplace" (Bonica 2012). The 
dataset of contributor records that was used to recover estimates is downloaded 
from the Federal Election Commissions Website (http://data.fec.gov). Some of the 
variables are provided by the Center for Responsive Politics 
(http://www.opensecrets.org). These variables are indicated by placing the 
string (CRP) before the variable name. If any of these variables are used, 
please attribute credit to the Center for Responsive Politics.
